       10. The vehicle of  claim 9 , wherein the sound selector selects a chord corresponding to the condition information of the vehicle from among a plurality of pre-stored chords. 
     
     
       11. The vehicle of  claim 10 , wherein the sound controller synthesizes the selected chord, the generated integrated formant filter, and the base sound to generate the driving sound. 
     
     
       12. The vehicle of  claim 9 , wherein the filter generator generates the integrated formant filter in consideration of a path between the speaker provided in the vehicle and a driver seat provided in the vehicle. 
     
     
       13. The vehicle of  claim 9 , wherein the filter generator analyzes the sound of the object to derive a spectrum distribution and generates a partial formant filter corresponding to each of one or more resonators of the object from the derived spectrum distribution.
